ROLLING SEAMS OF BOOTS AND SHOES.

Specification forming part of Letters Patent No. 33,515, dated August 11, 1563.

To all whom it may concern.-

Be it known that I, JOHN 0. WHITE, of Auburn, in the county of Cayuga and State of New York, have invented a new and Iniproved Machiche for Rolling; the Seams of Boots and Shoes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming apart of this specification, in which- Figure 1 represents a plan or top view of my Fig. 2 is a longitudinal vertical section of the same. l

' Similar letters of reference in both views indicate corresponding parts.

In the manufacture of boots and shoes, par-. ticularly of leather or morocco, it is essential,

. in order to produce good work, to rub the seams well down on the inner side. Up to the present time this operation has been performed entirely by'hand, with great exertion and loss of time.

The great object of this invention is to perform the operation of rubbing down or rolling the seams by machinery capable of being driven by other than human-power; and the invention consists in the arrangement of a roller-arm, connected by suitable mechanism with a rotary shaft, and working on a curved or straight bed, which supports the material to be rolled in such a manner that by imparting to the shaft a continuous rotary motion the roller assumes a reciprocating iectilinear motion,trave1in g repeatedly over the seam on the bed. The bed is adjustable to conform to the shape of difterent seams, and the pressure exerted by the roller on the seams can be increased or decreased by a simple arrangement of springs.

To enable those skilled in the art to make and use my invertion,,I will proceed to describe it.

A represents a frame, of metal or other suitable material, which is supported by legsB,

and which forms the bearings fora shaft, 0, to which a rotary motion is imparted by a belt running on the pulley D, or by any other suitable means. The shaft 0 carries a crank, a,-

which connects by a rod, 11, and arm 0 with a rock-shaft, d, and this rock-shaft connects by an arm, e, and link f with a sleeve, g,which is adjustable by means of a set-screw, h, on the roller-arm E. The outer end of this arm is forked, and forms the bearings for the axle of a grooved roller, 41, which travels on the bed F, and the rear or inner end of said roller-arm is supported by a grooved roller, j, the shaft of which has its bearings cn boxesk, that slide on the top of the grooved roller i in the outer end of the roller-arm, and by referring to Fig. 2 of the drawings it will be readily understood how, by raising the roller j, supporting the inuer end of the rollerarm, the outer end or grooved roller, '15, is depressed on the bed 1 and by lowering the roller 9' the pressure exerted by the grooved roller on the bed is diminished. The bed F consists of a metal bar, the surface of which is rounded, and which extends in an upwardly-inclined direction from the end of the frame A. The inclination of said bed is steeper than that of the roller-arm E, so that the grooved roller rises gradually as the arm advances, and when-said roller has reached its extrcmepssitioti the arm E is parallel with the bed.

tached to the frame A and forming a socket for the outer part, 0, and said outer part is so,

arranged that it can be turned round in the inner part, and that either of its surfaces can be brought under the roller 2. It is secured in the desired position by a set-screw, p, and

it is provided with two swivel-clamps, q, one on each surface, to hold the leather or other material to be rolled. These swivel-clamps are intended to stand just high enough to admit the seam of a boot or shoe, and they hold the work and prevent the grooved roller from striking the same too suddenly.- One surface of the outer part of the bed F is straight, and the other curved, to correspond to the shape of dift'erentseams. If desired, the bed can be accommodated to a great variety of Scams by substituting pieces of diiferent shapes for the outer part, 0.

p The bed F is made of two parts, 0 0, theinner part, 0, being rigidly atc What 1" claim as new, and desire to secure by Letters Patent,' is.-

1. The employment-or use of the reciprocating roller-arm E and stationary bed F, when '9' and springroller n, in combination with the roller-arm E and bed. F, constructed and operating substantially as and for the purpose set forth.

3. Making the outer part, 0, of thebed F adjustable by a set screw, 11, or other equivalent means, as and for the purpose described.

4.' The arrangement of the swivel-clamps q in combination with the bed F, constructed and operating in the manner and for the purpose snbstantially as specified.
